The powerpipe and larger meter are letting more air into the blower, which will push more cfm into the motor since the blower is working easier. More air into the same motor will increase boost since it now has more of a restriction.
Most PP users report a increase of 2-3 pounds of boost, we saw the same thing on our 93 Cobra.
